AUTGMATIC SWITCH.

Specification of Letters Patent.

Patented .l'uly 13, 1909.

Application filed March 3i., 1909. Serial No. 487,053.

To ali whom 'it may concern:

Bo it known that l, IVAN Dran., a citixcn of the United lStatcs, residingl at Brazil, in the county of Clay and Stato ol Indianay haro lnvcntcd ccrta'in now and usclul lm provcnicn ts in Automatic Switches, oi which thc following is a specification.

This invention relatos to railway applianrcs and particularly to a switch which may hc 'automatically 'operated oar or train.

The invention consists in ccrtain specific vnovel fcaturcs ol construction hiaoinal'tor lnlly dcscrihcd and claimed, and illostrz'ttcd' in. thcl acc()inpanyingdrz'twings, in which- Figure l is a plan vic/W olitho switch and operating devices` therefor with main. liuc open; Fig. 2 is a vertical transvcrsi` section on thc hrolton lino 2-2 olE Fig". l; Fig. 3 is a fragmentary' plan showing lho switch points indicatod in Fig, l with .main linol closcd, and Fig. his a vcrticfal dota-il ol' tho ship'i'iing dcvico. f

'lfhroughout thcI yfollowing dotail doscrip tion, and on tho scvoral 'figuras oll thc drawings si milail paris arc rclcrrcd lo hy like roi! crcncc characters.

The main lino ol track is indicatori at l() and thc switch at 1]. The switch includes a pair ol' movable switch points l2 ('onncctod lor simultaneous operation hy Ymoans olI a har 13 projccting latorally to thc ontsido ol' i thc switch.' ',lhc normal position ol tho switclnlcaving tho main linc l0 opon, is Vindi- Catod in llig. 1. ,Assuming that a car or train is approachinfbll thc switcli in thc dil-cction of thc arrow a and thc Samc is desired to take thc switch, thc switch will ho moved to tho position indicatori in Fig. 3.

A voi-tical shaft 14 is suitably iou'rnalod and braced upon coitain olA thc tics of thc railway track and has coniio'ctcd thcroto air operating arm l5 and at its lowor cnd is pro vided with a pinion lo. A11 operating rod 17 having; rack tooth 1S in mosh with said pinion lis mounted for sliding inovomcnt in a"nuinhcr of guides l?) connoctcd to as many tics as dcsircd. The rod 17 is pro- Vidcfl'with a cam. 2() adapted to cngagc With tho oitcr ond of thc har i3 to opor-atc thc latter in one direction against tho t0nw sion ol a sti-ong tcnsilc` springl 2l connoctid at ono ond to tho har i3` and Pat tho otliir' cnd to a tic orany othonsuitahlc lixcd point,

from a movingwill hc Jnovfd from thc position indicalod. in l lfnll lincs in Fig. l to tho position indicatod in dottcd lincs. During' such nlovcrncnt ol" (ho arm l5 thc pinion TG will opcratc tho roil 17 so to bring1 thc cani 20 into thc position indicatcd in Fig'. 3, oihcting tho Chango of thc switch points, and pcrlnitting` thc car or train to pass upon thc switch. Any conviniicnt moans may bc employed for mounting and opcrating tho ac tnator 22; As indicated diagralnniatically said .mcmhcr is pivotcd at 22 and is normally hold olcvatod hy moans of a catch 23 which may ho withdrawn from the actuator by a handlo 2l, against tho ton.- sion ol' a spring' 25. drawn l'roin. tho actuator tho` laltii' will drop into ong'aging position and al'tor oporation tlicrool' thc' actuator may ho opcratid hy hand or olhcrwisc inl o l ho position indicated in Fig'. l and in dottcd linosin liifr il. l'ho oppositeJ ond ol thc rod .Wis providrd with rack tooth Qi'which iirgjagrr a pinion 27 carriod by a sccond vertical shalt 2S. lor shalt has iorincctcd thorcto an. arm 2) whorchy tho rod l' may lio rcllirncd to its original position hy Contact ol' an actuator similar to that indicatcd hcroinlwlorc and lcarriod hy tho roar ond of (hc train or car.
